Series 3000MR/3000MRS Photohelic® Switch/GageCombines Differential Pressure Gage with Low/High Set-Points, Compact Size
Using solid state technology, the SERIES 3000MR AND 3000MRS Photohelic®
Switch/Gages combine the functions of a precise, highly repeatable differential
pressure switch with a large easy-to-read analog pressure gage employing the
durable, time-proven Magnehelic® gage design. Switch setting is easy to adjust with
large external knobs on the gage face. Gage reading is unaffected by switch operation
- will indicate accurately even if power is interrupted. Solid state design now results
in greatly reduced size and weight. Units can be flush mounted or surface mounted
with hardware supplied. 3000MR models employ versatile electromechanical relays
with gold over silver contacts - ideal for dry circuits.
For applications requiring high
cycle rates, choose 3000MRS models with SPST (N.O.) solid state relays. All models
provide both low and high limit control and include 18-inch (45 cm) cable assemblies
for electrical connections.
Compatible with air and other non-combustible, non-corrosive gases, they
can be used in systems with pressures to 25 psig (1.725 bar). Optional
construction is available for use to either 35 psig (2.42 bar) or 80
psig (5.51 bar).
Included Accessories: mounting ring, snap ring; 18" (45 cm) cable
assembly; (2) 3/16" tubing to 1/8" NPT adapters; (2) 1/8" NPT pipe
plugs; (4) 6-32 x 1-1/4" RH machine screws (panel mounting); and (3)
6-32 x 5/16" RH machine screws (surface mounting).
